My next greenhouse. Probably have to seal the dang thing but its all pvc frame so it wont rust. I was going to wrap a 5 tier resin shelving unit in plastic and add zippers but i got this thing on sale for 16.00 which is what i would pay for a roll of 4 mil plastic so im going to try it out. Im going run waterproof led light tape inside the unit.

Apparently I stole my current martha idea from you @microbe77! I'll do ya one further! If you plan accordingly and have enough room, one could start with one set of shelves and slowly expand outward. Adding shelving and shower curtains as you need space! All radial like the isolate myc, I emulate the myc.

Anyway, it's modular, so one could lower height of shelving etc.. I use shower curtains, heavy duty (thicker mil), usually made with microban, again, easily expandable and flexible to one's needs, plus they have magnet weights built in (helps keep yer plastic from going all willy nilly). One could run a piece of cord through the top, draw the curtains tighter than the surface area of the top shelf, stick a pvc pipe stuffed with poly in, and BOOM a lil extra FAE with a homemade particle filter, plus that way one could easily remove from shelving for it's WEEKLY washing. Right now I'm using cable ties to get all the variables lined up proper!

I ordered 2 of them, the picture is not the configuration of the unit so im joining the 2. It is not pvc frame either so im going to paint on the tubing with a premium paint so it will not rust.

Title says it all. I have read a ton of threads and the answer does not seem clear. I would imagine that the change in temperature with the room and the martha would be enough but I wanted some more input. I'm over SGFG's, plus I could convert them to monos..

Bump! What is everyone using to bring FAE in to the Martha? I was thinking of using an air purifier or a small centrifugal fan with a hose to bring fresh air in from outside the tent. I currently use a cool mist humidifier (outside the tent w/ hose) and a clip fan inside to keep air stirred up but have yet to use any thing to bring fresh air in. I believe my Martha is staying too wet as the racks are constantly dripping. Maybe this is where my contamination issues are coming from I don't know
